  Considering the situation where a device for measuring biological information such as blood glucose level is used, it is not limited to daytime, and there are many occasions when the surroundings are relatively dark, such as at night. Therefore, the convenience of the user when attaching / detaching a sensor for measuring biological information to / from the apparatus main body is a problem directly related to the operability of the measuring apparatus itself. On the other hand, as is especially true for portable measuring devices, it is demanded to suppress the power consumption of the measuring device itself as much as possible from the recent increase in environmental awareness.

  That is, as in the prior art, the convenience of the user is improved by installing an illuminating device (such as a light-emitting diode) that illuminates the blood collection site in the measuring device. The power supply life of the measuring device is shortened.

  The present invention has been made in view of the above problems, and provides a lighting function that improves user convenience in a measuring apparatus that measures user biometric information, and can increase power consumption as a measuring apparatus. The purpose is to suppress as much as possible.

  In the present invention, in order to solve the above-described problem, a sensor for measuring light emitted from a light source unit that is already functioning as a light source for some configuration in a biological information measuring device via a light guide member. It was decided to lead to a predetermined place where is attached and detached. Thereby, it is not necessary to provide a new light source for attaching and detaching the sensor, and it is possible to avoid an unnecessarily high power consumption in the measuring apparatus.

Specifically, the present invention relates to a biological information measuring device that measures a user's biological information, the device main body, an attachment / detachment unit that is provided in the device main body and that attaches / detaches the sensor that measures the biological information, The sensor attaches and detaches light emitted from the light source unit and a light source unit that functions as a light source for the configuration of the biological information measuring device other than the detachable unit at a position separated from the detachable unit in the apparatus main body. And a light guide member that leads to a predetermined position in the vicinity of the attaching / detaching portion.

  The biological information measuring apparatus according to the present invention, for example, by spotting, absorbing, etc., a sample for measurement with respect to the sensor in a state where the sensor for measurement is attached to the detachable part of the apparatus main body. A signal related to biological information to be measured is transmitted from the sensor to the apparatus main body. Based on this signal, the biological information of the biological information finally obtained on the apparatus main body side is generated. In the biological information measuring apparatus having such a configuration, the user needs to attach the sensor to the detachable part when measuring desired biological information, and to remove the sensor when the measurement is completed. Therefore, when the user operates the measuring apparatus, the attaching / detaching operation of the sensor to / from the apparatus main body is considered to be an element that greatly affects the operability of the measuring apparatus and the convenience of the user.

  Here, in the biological information measuring device, the light source unit functions as a light source for the configuration of the biological information measuring device other than the detachable unit at a position separated from the detachable unit. That is, the light source unit is already incorporated as one configuration of the biological information measuring device, and is not newly incorporated in the device in order to solve the above problem. Therefore, in the biological information meter device, a configuration that is already incorporated and functions as a certain light source corresponds to the light source unit.

  However, the light guide member is disposed between the light source unit and a predetermined position in the vicinity of the detachable unit, so that light of the light source unit that is not originally illumination for the detachable unit is guided to the vicinity of the detachable unit. It is possible to support the attachment / detachment of the sensor to / from the attaching / detaching portion. In particular, the light guided by the light guide member effectively supports the user's sensor attaching / detaching operation in an environment where the surroundings are dark, and in a configuration that directly consumes power for light emission for the support. Therefore, the power consumption as the biological information measuring device is not increased unnecessarily. In addition, the predetermined position may be any position as long as the light transmitted from the light guide member is irradiated from the predetermined position and can support the detaching operation of the sensor. Such a predetermined position is, for example, a position in the vicinity of the attachment / detachment part suitable for the support. The predetermined position may include the position of the detachable part itself.

  The biological information measuring apparatus may further include a display that displays biological information measured through the sensor, and in this case, the light source unit may be a backlight that functions as a light source of the display. . The backlight is a light source that makes it easy for the user to see the display on the display, that is, a configuration that is already incorporated in the measurement apparatus. Therefore, in the biological information measuring apparatus having such a configuration, the light emitted from the backlight is guided to the predetermined position by the light guide member, thereby ensuring illumination at the predetermined position without newly providing a light source. be able to.

  In this case, the attaching / detaching portion may be provided on a side surface of the apparatus main body, and the light guide member may be configured to have a length for guiding the light of the backlight to the predetermined position. That is, by making the length of the light guide member appropriate, it is possible to reliably carry the light of the backlight to a separated position where the detachable portion is provided.

  Moreover, in the biological information measuring device up to the above, an operation unit for the user to operate the biological information measuring device is further provided. In this case, when the operation unit is operated by the user, the light source unit The light may be emitted and the light guided to the predetermined position by the light guide member. That is, when the user intends to operate the biological information measuring device via the operation unit, the light emitting unit emits light triggered by the contact with the operation unit, so that the sensor can be attached to the attachment / detachment unit, Desorption can be easily performed.

  The biological information measuring device may be configured such that when the sensor is attached to the attachment / detachment unit, the light source unit emits light and the light guide member guides the light to the predetermined position. . According to this configuration, since light is guided to a predetermined position through the light guide member after the sensor is mounted, the user can easily perform a treatment on the sensor after mounting, for example, spotting a biological sample. In this case, light emission by the light source unit may be performed at the same time as or after the sensor is mounted on the detachable unit.

  Further, in the biological information measuring device described above, the biological information measuring device is a device for measuring a user's blood glucose level, and in this case, the blood of the user is spotted on the detachable portion and the blood glucose level is adjusted. A configuration in which a blood glucose level measurement sensor that outputs a corresponding current output is attached or detached may be used. The biological information measurement device may be a device that can be carried by a user. These are merely examples, and the biological information measuring device according to the present invention is not limited to such an embodiment.

  Next, it is possible to grasp the present invention from the aspect of the illumination method in the biological information measuring apparatus. That is, the present invention provides a biological information measuring apparatus for measuring a user's biological information, comprising: an apparatus main body; and a sensor for measuring biological information of the user, which is attached to and detached from the apparatus main body from the outside of the apparatus. An illumination method for illuminating the vicinity of the attachment / detachment unit, wherein the light source unit functions as a light source for the configuration of the biological information measuring device other than the attachment / detachment unit at a position separated from the attachment / detachment unit in the apparatus main body. A light guide provided between the light source unit and a predetermined position in the vicinity of the detachable part where the sensor is attached and detached. And a second step of leading to the predetermined position through the member. Also in the illumination method according to the present invention, as in the case of the biological information measuring device, it is possible to provide illumination when the sensor is attached / detached without providing a new light source for attaching / detaching the sensor. Thus, the operability of the apparatus can be improved and the convenience can be improved without unnecessarily increasing the power consumption in the apparatus. In addition, the technical idea disclosed about the said biological information measuring device is applicable also to the illumination method which concerns on this invention similarly.

  In addition, the present invention can be grasped from the aspect of a biological information measuring method using a biological information measuring device. That is, the present invention provides a measurement for measuring a user's biological information in a biological information measuring device having a device main body and a sensor for measuring the user's biological information, which is attached to and detached from the device main body from the outside of the device.

  Hereinafter, a blood glucose level measuring apparatus corresponding to a biological information measuring apparatus according to an embodiment of the present invention will be described with reference to the drawings. In addition, the structure of the following embodiment is an illustration and this invention is not limited to the structure of this embodiment.

<Outline of blood glucose level measuring device>
FIG. 1 is a diagram showing an appearance of a blood sugar level measuring apparatus 1 according to the present invention. The blood sugar level measuring device 1 is a portable measuring device configured so that a diabetic user can measure blood sugar by himself / herself. As shown in the figure, the blood glucose level measuring device 1 has an elongated casing 2 (device main body) that is about the size of the user's palm, thereby improving the operability of the user and measuring results as will be described later. By enabling appropriate and quick management and display, it is configured to contribute to blood glucose management of the user.

  Specifically, FIG. 1A shows the front side configuration of the blood glucose level measuring apparatus 1, and FIG. 1B shows the back side configuration. On the front panel 3 of the housing 2, a liquid crystal screen 4 for displaying measurement results and the like is provided. Further, a test piece for measurement used in the blood glucose level measuring device 1 and a test piece insertion groove 10 for inserting a test piece (shown in FIG. 5 to be described later) are inserted at the end of the housing 2 (corresponding to the detachable portion according to the present invention). Is provided). This test piece is provided with a sensor that reacts with glucose in the blood collected from the user and outputs an electrical signal. The user drops his / her blood on the sensor when measuring the blood glucose level. Thus, measurement by the blood sugar level measuring apparatus 1 is performed. As the sensor, for example, a sensor using glucose oxidase (GOD) as an oxidoreductase and using a hydrogen peroxide electrode as a signal output electrode can be employed. Note that the configuration of the test piece itself is according to the prior art and is not the core of the present invention, and therefore detailed description thereof will be omitted.

Further, as shown in FIG. 1B, on the side surface of the panel 3 on the back side of the housing 2, an operation button 7 for installing the blood sugar level measuring device 1 and a blood sugar level measuring device 1 and an external device such as an external device are arranged. A communication port 8 is provided to connect the connected computer or the like so as to be communicable. The operation button 7 enables operations for all processes performed in the blood glucose level measuring apparatus 1 by a combination of various operations such as a pressing operation, a sliding operation, and a pressing state holding operation by the user. This corresponds to the operation unit according to the invention.

  Further, the blood glucose level measuring apparatus 1 is provided with a control unit for controlling various processes performed there. As main control units in the blood glucose level measuring apparatus 1, as illustrated in FIG. 2, a measurement control unit 20, a management control unit 30, a display control unit 40, and an external communication unit 50 are provided. Each control unit is realized by a computer program that is formed in the blood glucose level measuring apparatus 1 and that is executed on a computer including a CPU, a memory, a hard disk, and the like (not shown). Further, the above-described liquid crystal screen 4, operation buttons 7, and communication port 8 are also appropriately connected to the respective control units shown in FIG. 2, thereby displaying a measurement result to the user and a measuring device for operating instructions from the user. Program processing relating to transmission of data, communication of data accumulated in the blood glucose level measuring apparatus 1 to the outside, and the like are executed. Hereinafter, the configuration of the control unit of the blood sugar level measuring apparatus 1 according to the present invention will be described.

  As described above, the control unit of the blood glucose level measuring apparatus 1 mainly performs the measurement control unit 20 that performs measurement control related to blood glucose level measurement, the management control unit 30 that performs management control related to the measurement result, and performs display control of the measurement result. The display control unit 40 and the external communication unit 50 that performs communication control with the outside of the measuring apparatus are formed. However, a configuration including a control unit other than this may be employed. Specifically, the measurement control unit 20 includes a test piece confirmation unit 21, a blood glucose level measurement unit 22, a measurement result recording unit 23, and a hypoglycemia alarm unit 24. The test piece confirmation unit 21 is a functional unit that confirms whether or not the above-described test piece for blood glucose level measurement is set on the blood glucose level measurement device 1 side and is in a measurable state, and the blood glucose level measurement unit 22 Is a functional unit that measures the blood glucose level of the user based on the confirmed output signal from the test piece. The measurement result recording unit 23 is a functional unit for storing and recording the result measured by the blood glucose level measuring unit 22 in a recording device (memory) in the blood glucose level measuring device 1. Further, the hypoglycemia alarm unit 24 is a functional unit that notifies the user that hypoglycemia is present when the measured result is lower than the reference range related to the appropriate blood glucose level.

  In addition, the management control unit 30 includes a state flag setting unit 31, an elapsed time setting unit 32, and a parameter setting unit 33. The state flag setting unit 31 is a function for setting a flag relating to the state of the body at the time of blood sugar level measurement that affects the blood sugar level of the user. With this function, the blood sugar level management of the user is made efficient. Can do. In the present embodiment, state flags relating to after exercise, before meal, and after meal are adopted as a flag representing the state of the user's body. The setting of the status flag is performed according to the content displayed on the liquid crystal screen 4 by the user operating the operation button 7. Specifically, the user selects one of four status flags, that is, a post-exercise flag, a pre-meal flag, a post-meal flag, and no status flag, and the status flag corresponding to the selection is associated with the measured blood glucose level. And recorded in the blood glucose level measuring apparatus 1. Since these state flags are flags relating to the body state having a strong relationship with the blood glucose level of the user, it is extremely useful for blood glucose level management to associate the state flag with the blood glucose level measured in this way.

Note that the display unit control unit 40 displays these status flags on the liquid crystal screen 4. The display control unit 40 is a control unit for displaying a blood glucose level measurement result by the measurement control unit 20, a state flag set by the management control unit 30, and the like on the liquid crystal screen of the blood glucose level measurement device 1. FIG. 3 shows an example of display on the liquid crystal screen 4 performed by the display control unit 40. In this display screen example, icons and numerical values are collectively displayed for explanation. On the left side of the liquid crystal screen 4 is a rectangular display area, which is formed with a graph display area DR1 for displaying the measurement result in a graph, and a measured value display area DR2 for displaying the measured blood sugar level and the like at the center. And an icon display region DR3 for displaying icons having various meanings and a predetermined elapsed time are formed around the measured numerical value display region DR2. The icons displayed in the icon display area DR3 include the hypoglycemia alarm icon “HYPO”, the post-exercise flag icon Ic1, the pre-meal flag icon Ic2, and the first icon Ic3 for the post-meal flag as described above. , A second icon Ic4 is included. Further, in the icon display area DR3, the post-meal elapsed time Et is displayed adjacent to the first and second icons for the post-meal flag. In addition, since the display control itself by the display control unit 40 does not form the core of the present invention, detailed description thereof is omitted in this specification.

  When the state flag set by the state flag setting unit 31 is a post-meal flag, the blood glucose level measuring apparatus 1 according to the present embodiment can also set information regarding the amount of meal consumed in the meal. Specifically, in the subjectivity of the user, when the full-meal amount is taken as 100%, the user selects one of the three types of 50%, 80%, and 100% as the meal amount. it can. In the blood glucose level measuring apparatus 1 according to the present embodiment, the selection of the postprandial flag is represented by the display of the first icon Ic3 for the postprandial flag in the icon display area DR3 of FIG. Along with the display of the flag second icon Ic4, the number of bars (bars) displayed in the icon is changed. For example, when the amount of meal is 100%, the number of bars is three (the state shown in FIG. 3), and when it is 80% and 50%, the number of bars is two and one, respectively. In this way, by associating the data relating to the amount of meal with the post-meal flag, the user can know what amount of meal the blood glucose level was measured, and the relationship between the amount of meal and the blood glucose level can be determined. As well as understanding, it becomes easier to manage health related to blood sugar levels, such as adjusting the amount of meals.

  Next, the elapsed time setting unit 32 is a functional unit that sets an elapsed time from the end of the meal when the state flag setting unit 31 sets the post-meal state flag. Prior to the measurement, the elapsed time setting unit 32 sets an elapsed time counter that automatically counts the elapsed time from the end of the meal, and determines the elapsed time counted by the counter as the blood glucose of the measurement result at that time. Associate with a value. This elapsed time is displayed as the post-meal elapsed time Et in the icon display area DR3 of FIG. Thereby, in addition to the above-mentioned meal amount, the user can recognize how much time has passed since the end of the meal, so that the user can recognize the measured blood sugar level, which makes it easier to perform health management regarding the blood sugar level. The parameter setting unit 33 is a functional unit that sets various control parameters used in the blood sugar level measuring apparatus 1. Examples of the parameters include the date and time used in the blood glucose level measuring apparatus 1 and the tester container opening date described later. Such a function unit included in the management control unit 30 allows the user to efficiently manage the measurement results related to his / her blood glucose level.

  The external communication unit 50 is a control unit that transmits information such as a result measured by the measurement control unit 20 and a status flag managed by the management control unit 30 to the outside of the blood glucose level measuring apparatus 1. In the blood glucose level measuring apparatus 1 according to the present invention, the communication control by the external communication unit 50 does not play a central role, and therefore, in the present specification, it is described that the external communication function is exhibited by the external communication unit 50. I won't go into details about that.

  Here, the configuration in the vicinity of the test strip insertion groove 10 in which a test strip for measuring blood glucose level is inserted into the blood glucose level measuring device 1 will be described with reference to FIGS. FIG. 4 is an enlarged view of the appearance of the blood glucose level measuring device 1 in the vicinity of the test piece insertion groove 10, and FIG. 5 is a top view of the blood glucose level measuring device 1 with the front panel 3 removed. FIG. 6 is a cross-sectional view taken along the line AA in FIG. 5 (the panel 3 is indicated by a dotted line). The blood glucose level measuring apparatus 1 is provided with a backlight 41 on the back surface of the liquid crystal screen 4. The backlight 41 has a plate shape, and receives light from a power source for blood sugar level measurement in the blood sugar level measuring apparatus 1 to emit light. The backlight 41 is of an edge light type having a light source on the end side opposite to the test piece insertion groove 10 in the longitudinal direction of the blood glucose level measuring apparatus 1, and corresponds to the light source unit according to the present invention.

  Here, an illumination opening 45 is provided on the upper side of the test piece insertion groove 10 provided on the side surface in the longitudinal direction of the housing 2 of the blood sugar level measuring device 1 (in the direction of the device front side where the liquid crystal screen 4 is disposed). It has been. The light guide member 42 is provided in the blood glucose level measuring device 1 so that the one end 42 a of the light guide member 42 is exposed at the illumination opening 45. The light guide member 42 has an elongated shape having end portions 42a and 42b through which light can enter and exit, and is a member capable of emitting light incident from one end from the other end. The side portion of the light guide member 42 (the portion extending in the longitudinal direction other than the end portion) is subjected to surface treatment so that light incident on the inside is not easily leaked from the side portion. preferable. The light guide member 42 formed in this way is disposed adjacent to the backlight 41 as shown in FIGS. 5 and 6 so that one end 42b of the light guide member 42 can enter the light emitted from the backlight 41. The On the other hand, the remaining one end 42 a is disposed so as to be exposed to the outside of the blood glucose level measuring device 1 through the illumination opening 45. That is, the light guide member 42 includes a backlight 41 of the liquid crystal screen 4 disposed in the center of the front panel 3 and an illumination opening 45 disposed on the side of the housing 2 as shown in FIG. 1A. It will be arranged in the blood glucose level measuring device 1 so as to be connected.

  In the blood glucose level measuring apparatus 1, as shown in FIG. 6, the light guide member 42 is arranged so that it is slightly inclined, that is, in FIG. 6, one end 42b is positioned slightly higher than the one end 42a. Yes. Thereby, the direction of the light guided in the light guide member 42 is defined. In the case of the present embodiment, due to this inclination, the light from the one end 42a is irradiated slightly downward in FIG. 6, that is, the side where the test piece exists. In this way, by adjusting the inclination of the light guide member 42, it is possible to adjust the light irradiation range from the one end 42a to some extent.

  Further, the test piece insertion groove 10 is provided with a guide member 43 having a protruding portion slightly protruding outside the apparatus on the lower side, and the user can use the protruding portion of the guide member 43 to perform a test. The strip can be easily slid into the test strip insertion groove 10. Note that the test piece inserted into the test piece insertion groove 10 is in a state of being electrically connected to the connection portion 44 provided at the back of the groove, so that the test piece confirming portion 21 described above can test the test piece. The insertion confirmation and the transmission of the measurement result of the test piece to the apparatus main body, that is, the blood glucose level measurement by the blood glucose level measurement unit 22 can be performed.

  In the blood sugar level measuring apparatus 1 configured as described above, the light of the backlight 41 that is the light source of the liquid crystal screen 4 is irradiated to the outside of the apparatus from the illumination opening 45 through the light guide member 42. . Since the guide member 43 is positioned below the illumination opening 45, the illumination illuminates the vicinity of the entrance portion of the test piece insertion groove 10, and as a result, the test to the blood glucose measuring device 1 is performed. The mounting of the piece is easily accepted. In particular, when the blood glucose level is to be measured in a dim room such as at night, the illumination method using the light of the backlight 41 through the light guide member 42 is extremely useful. Moreover, in the blood glucose level measuring apparatus 1 according to the present invention, a dedicated illumination device for inserting a test piece is not provided in the interior thereof, but the backlight of the liquid crystal screen 4 is only provided through the light guide member 42. It has a configuration that makes effective use of light. Therefore, the configuration of the measuring apparatus can be simplified, and the current consumption required for illumination is substantially unnecessary, which is preferable from the viewpoint of securing the driving power supply of the measuring apparatus. In particular, it is to be understood that the portable blood glucose level measuring apparatus 1 is a practically preferable technique since securing of the drive power supply and improvement in user operability are compatible. In the above embodiment, the backlight 41 and the light guide member 42 are separately configured and arranged adjacent to each other, but instead of this configuration, the backlight 41 and the light guide member 42 are continuous. You may form in one plate shape.

Here, the light emission by the backlight 41 is performed according to the operation of the operation button 7 by the user. Specifically, the backlight 41 can be turned on by pressing the operation button 7 or sliding the operation button 7. As a result, light emitted from the backlight 41 travels through the light guide member 42 and is emitted from the illumination opening 45. That is, the operation button 7 is a button for transmitting a user instruction to perform each control described with reference to FIG. 2, and also a button for irradiating light from the illumination opening 45.

  Further, in the above-described embodiment, the illumination from the illumination opening 45 when the test piece is mounted is mentioned. However, when the mounted test piece is removed, the illumination can be performed by operating the operation button 7. You may go. Furthermore, the user's blood spotting on the test piece may be performed before the test piece is mounted or after the test piece is mounted. In the latter case, in a state where the test piece is mounted in the test piece insertion groove 10, the user operates the operation button 7 to emit the backlight 41 and irradiate light from the illumination opening 45. The spotted blood spot on the test piece can be illuminated. As a result, the user's blood spotting operation can be easily performed. As another method, regardless of the presence or absence of illumination when the test piece is installed, the test piece is automatically backed up at the same time as the test piece is installed in the test piece purchase groove 10 or at a certain time after the installation. The light 41 may emit light.

Here, it is not preferable that the backlight 41 is always lit from the viewpoint of power consumption suppression. For example, the power consumption by the backlight 21 may be suppressed by controlling the backlight 41 to light only for a predetermined time after the user performs some operation on the operation button 7. In order to effectively support the sensor desorption operation of the user, it is ^{preferably, 1mCd / m 2 ~2000Cd / m} 2 intensity at the illumination opening 45 is 1μCd / m ² ~10000Cd / m ² More preferably, it is more preferably 1 Cd / m ^{2 to} 100 Cd / m ² .

  In the above embodiment, the light from the backlight 41 that is the light source of the liquid crystal screen 4 is used as the light source for inserting the test piece by using the light guide member 42. When there is a light source other than the light 41, the configuration belonging to the category of the present invention is a configuration in which light emitted from the light source is guided to the illumination opening 45 by the light guide member.

  Next, a blood sugar level measuring apparatus 1 according to a modification of the present embodiment is shown. 7 and 8 are cross-sectional views showing the main parts of the measuring apparatus 1 according to this modification. FIG. 7 is a diagram schematically showing a horizontal section (transverse section) according to the blood glucose level measuring apparatus 1, and FIG. 8 is a diagram schematically showing a vertical section (vertical section) according to the measuring apparatus 1. . The blood sugar level measuring apparatus 1 in the present modified example has an operating part 46 for operating the blood sugar measuring apparatus 1, a light source 47 for illuminating the operating part 46, and light from the light source 47 in the test piece insertion groove 10 '.
